Keterkaitan Struktur Komunitas Makrozoobentos Antara Habitat Mangrove, Lamun dan Reef Crest di Pulau Kelapa Dua, Kepulauan Seribu

Abstract

Makrozoobentos is fauna invetebrate benthic organism by sieving with size 0,5 mm. The aim of this research is to connectivity the macrozoobentos community structure along gradient of mangroves, seagrass, and reef crest habitat in Kelapa Dua Island. Habitat conditions was taken into account for sampling strategy. Benthic fauna samples were taken by means of a corer. The community structure of macrozoobentos is indicated by parameter of number of species, abundance and biomass (SAB). Analysis of similarity of the SAB parameter was mainly used to evaluate the connectivity of the three main coastal habitats. The highest number of species and biomass of macrozoobenthos was found in the seagrass habitat, while the most abundance was in the reef crest habitat. The most abundance and biomass species which mainly contributes on the habitat connectivity were Syllis sp, and Paraonis sp. The analyzes showed that seagrass habitat was closely connected with reef crest than mangrove.
